A rotorcraft having an enhanced configuration in which a simple wing and a
propulsive anti-torque system are combined is disclosed. The propulsive
anti-torque system includes an anti-torque thruster system in which a
variable pitch fan is installed internal to the tail boom of the
rotorcraft and an anti-torque thruster nozzle is mounted at the extremity
of the tail boom. The fan is driven directly from the main rotor drive.
The configuration and location of the fan allows the primary exhaust from
the engine to be mixed with the compressed air flow from the fan. The
mixed air flow from the fan and the engine passes through the tail boom
and out the thruster nozzle.
